A 34-year-old man has been arrested by police investigating eight sexual assaults in London.
The Metropolitan Police said the man from Lambeth was detained on Thursday and remains in custody.
Officers are continuing to appeal for witnesses and information following the assaults in the Clapham and Brixton Hill areas of the British capital.
The attacks have targeted lone women late at night in residential areas and all victims were aged in their 20s and 30s.
Superintendent Rob Applegarth, of Lambeth borough, said: "We are aware of eight assaults which we are linking at this early stage.
"We have increased police patrols in Clapham and Brixton Hill and urge women to think of their personal safety".
Another man was arrested and then released on bail on Wednesday but police were still looking for other people.
The first incident happened on Clitheroe Road at about 11.30pm on October 9th when a 23-year-old woman was grabbed and sexually assaulted. She managed to raise the alarm and the suspect ran off.
Nearly two hours later, a 30-year-old woman was approached by a man as she walked along Deauville Court. She asked him to leave her alone but was assaulted before he walked away.
On October 22nd, a 32-year-old walking along Trent Road at about 9pm was followed and assaulted.
Four days later, a 35-year-old woman was grabbed from behind as she walked home along Arodene Road at about 7pm.
Less than an hour afterwards, a 26-year-old woman was attacked on the doorstep of her home on nearby Rosebery Road - and the CCTV video released shows her being assaulted as she tried to get inside.
Later that same evening, a man exposed himself to a 28-year-old woman as she arrived at her house.
The two most recent attacks happened on 28 October. The first saw another 28-year-old woman grabbed by a man as she walked home on Southall Road. She screamed and he fled.
Then, three hours later, a 31-year-old woman was walking home when a man forced her into a block off flats on Sudbourne Road. The man sexually assaulted her and ran off.
